HERNIAL TRUSS.

SPECIFICATION forming part Of Letters Patent NO. 674,598, dated May 21, 1901.

Application filed June 4, 1900. Serial No, 19,024. (No model.)

T all whom it may concern:

Beit known that I, .TOEN WALLACE BUN- KER, of Farmington, in the county of Franklin and State of Maine, have invented a new and useful Improvement in Trusse's, of which the following is a specification.

vMy invention relates to an improvement-in trusses for treating hernia or rupture, and has for its object to provide a device which is 1o simple,light,andinexpensive in construction, easy to wear, and which will adjust itself so as to compensate for vibration in every movement of the body, and by its elastic pressure will properly supportthe hernia and hold the torn parts so closely and evenly that they will readily unite and heal.

The invention consists in the construction, combination, and arrangement of the several parts, as herein more fully described and spezo cifically claimed.

Referring to the drawings, Figure lis a perspective view of my invention. Figa 2 is a cross-section thereof.

In the drawings, in which like letters of reference denote like parts throughout the several views, A represents the pad of the truss, made, preferably, circular in shape and of wood; but it may be made in any other shape and of any other suitable material. The in- 3o ner face B of the pad A is fiat and has rounded edges C, and the outer face D is also at and provided with a ring E, secured theretol by means of plates F, which are secured bymeans of screws F'. G G G2 are a series of springs, preferably three in number, one end attached to the pad A, then wound around the ring E, as at H, and the opposite end formed into a loop I.

K is a belt the ends of which are attached 4o to the looped e'nds of .the springs G G', and

Y Lisa crotch-strap, one end attached to the said belt andthe opposite end attached to the loop I of spring G. When the pad isin use and the belt and crotch-strap are attached to the springs G G' G2, they will cause them to be moved outward and assume a position at 'substantially a right angle to the front surface of the pad, and this movement will cause the pad to move inward and bear against the hernia with a firm but yielding', even, and continuous pressure and support the hernia in all positions that the body of the wearer of the truss may assume and at the same time allow a free movement of the limbs.

The truss can be used for a hernia on either the right or left side, or two trusses can be used, one on each side, and although I have illustrated three springs the number may be increased or diminished as is found desirable.

I do not wish to be limited to the precise details of construction as herein shown and described, as the same may be varied somewhat without departing from the spirit of my invention.

Having thus described myinvention, what I claim is- A truss comprising a pad, a ring secured to the outer face thereof, springs mounted on said ring one end bearing on the pad, and the opposite free end connected to the ends of the belt and crotch-strap, said free ends moving outward and pressing the pad inward when tension is applied, substantially as described.

JOHN WALLACE BUNKER.
